Description
Summary:Summary form only given, as follows. Two and three-dimensional modeling of exploding Z-pinch wires as well as the imploding Z-pinch wire array is important to provide insight into the relevant issues for designing high-power Z-pinch configurations. We present several calculations done with the MHD modeling capability available within the ALEGRA framework for parallel shock-physics computations. A set of wire explosion calculations illustrates the extreme sensitivity of these configurations to mesh resolution. Use of the ALE capability in ALEGRA will be illustrated. An additional set of calculations investigating the run in and stagnation of an initial merged-wire sheath configuration will be compared with previous calculations and experimental results.
